I²C bus interface
Introduction
The I²C bus interface serves as an interface between the microcontroller and the serial I²C
bus. It provides both multimaster and slave functions, and controls all I²C bus-specific
sequencing, protocol, arbitration and timing. It supports fast I²C mode (400 kHz).

General description
In addition to receiving and transmitting data, this interface converts it from serial to parallel
format and vice versa, using either an interrupt or polled handshake. The interrupts are
enabled or disabled by software. The interface is connected to the I²C bus by a data pin
(SDAI) and by a clock pin (SCLI). It can be connected both with a standard I²C bus and a
Fast I²C bus. This selection is made by software.
